I enjoy solving sudokus in which some clues are part of the puzzle meaning that they are unknown in the beginning. In this killer sudoku all cages have one of two (initially unknown) sum values. The difficulty should be around 3/5. Feel free to tell me in the comments how you like it. Happy solving!

- Normal Sudoku rules apply.

- Killer cage: Digits in a killer cage do not repeat and sum to the clue in the top left. Each cage in the grid has either the total X or Y which have to be determined by the solver.

- Little killer: Digits on a marked diagonal sum to the little killer clue outside the grid. (If there is no conflict with other rules, digits on the diagonal may repeat.)

- XV: Digits joined by a V sum to 5. Digits joined by an X sum to 10. (Not all V and X are given.)

- Dots: Digits joined by a black dot have a 1:2 ratio. Digits joined by a black 3-dot have a 1:3 ratio. (Not all dots are given.)
